Frequently Asked Questions about projfwd()
Is the projfwd() function free to use in SimLab?
The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open projfwd() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use projfwd()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The projfwd() function requires no MATLAB® license or desktop software download.
What does projfwd() do?
Forward map projection (proj4-backed): convert geographic (lat, lon) to projected (x, y) coordinates. It is a MATLAB®-compatible mapping function available in SimLab with the same calling syntax as MATLAB® — typically: [x, y] = projfwd(proj, lat, lon).
Can I run projfwd() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls projfwd(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
